BALLAST-DRESSER.

Specification of Letters Patent.

Patented Dec. 13, 1910.

Application filed June 2, 1910. Serial N 0. 564.630.

To all whom it may concern:

Be it known that we, THERON S. CAF- FERTY and JOHN F. MARKLE, citizens of the United States, residing at Union, New York, and Chanute, Kansas, respectively, have invented certain new and useful Improvements in Ballast-Dressers, of which the following is a specification.

Our invention relates to a ballast dresser, that is for leveling and finishing the surfaces of ballasted railway tracks, and is an improvement u on U. S. Patent 912282 granted to T. Cafl'erty on the 16th of February 1909.

In the accompanying drawing of which Figure 1 is a part vertical section, and Fig. 2 a detail of the machine we show a flat car with the adjusting mechanism combined with a leveling member or dresser bar only slightly different from that shown in the patent aforesaid. The dresser bar is shown at A, and may consist of a straight bar with notches a, to allow it to pass over the railway rails, and we may utilize a shoulder dresser B which is removably connected to the bar A substantially as shown and described in the Cafferty patent. The top of the car which supports the mechanism is shown at C. Heavy springs 0 are located between the bar A and the bottom of the car so as to keep the bar pressed downward strongly against the surface of the roadbed when the device is in use. WVe utilize braces (Z to revent displacement of the bar in its up and down movement. The bar is supported by vertical uprights e passing through openings in the car bottom and these uprlghts are provided with keys to limit the downward movement of the bar A. A chain or cable 9 extends from the uprights to a piston h held within a cylinder 71, the cable passing over guiding rollers is. A connection is'made with a train line air pipe m to a cylinder 42, and from this cylinder a pipe 0 extends to the cylinder 2'. A two-way valve p is located in the pipe 0.

hen it is desired to operate the dresser board to lift the same the two-way valve 79 is turned to allow the pressure of air to enter the cylinder 2', which presses against the piston l1, forcing it to the rear and lifting the bar A. When it is desired to lower the bar the valve 79 is turned, which exhausts the air from the piston '11 and the weight of the board combined with the pressure of the springs a will force the bar against the track, and as the car moves the lock bolt when pressed inward.

In Fig. 2 we show a plate Z inclined laterally and secured to the dresser bar A. This plate may be removed and reversed in position, and its function is to cause the material to be forced laterally from one side of the track to the other, and it may be set to secure this action in either direction.

hat we claim is:

1. In combination with a dresser bar, a laterally inclined plate secured thereto, substantially as described.

2. In combination with a dresser bar, a laterally inclined plate secured thereto, said plate being reversible, substantially as described.

In testimony whereof, we affix our signatures in presence of two witnesses.
